UHPGRC

Ultra High Performance Glassfibre Reinforced Concrete offers several improvements over traditional Spray Process GRC.

Developed by the PBS Synergies group in partnership with other manufacturers and supply partners, UHPGRC offers beneficial material properties.

Higher flexural strengths

Based on the simultaneous spray methodology, advanced and complex additives are included within the concrete matrix, along with the use of specially developed high-performance alkali-resistant fibres.

This combination results in a mix design with flexural strengths approximately 30% higher than standard GRC grades as defined by the International Glassfibre Reinforced Concrete Association (GRCA), and those detailed in BS EN 15191.

 

Superior long term performance

It is documented in virtually all published works that traditional Spray Process GRC loses its ductility over time. This process is reduced considerably in our UHPGRC mixes.

The use of advanced polymers and admixtures in these mixes has resulted in ultimate strength loss being reduced from the accepted 60% to a more manageable 30%. This allows designers and engineers a more conservative approach when carrying out Finite Element Analysis and factoring in approximated flexural bending strength decline. All strength losses are supported by extensive laboratory testing to EN 1170-8 (derived in-house method) carried out in accordance with ISO/IEC 17025:2017 requirements.

Visually, all elements will also retain their supplied appearance longer due to specially designed surface sealants applied during the manufacturing process.

Highest levels of quality control

All our UHPGRC is made to the very strictest quality control based on both our and our global partners extensive expertise. Our unique approach to quality covers:

  • Independent quality control by non-production based team member.
  • Daily flexural testing to EN 1170-5 carried out by UKAS-accredited external laboratories.
  • Weekly density and water absorption testing to EN 1170-6 by UKAS-accredited external laboratories.
  • Proof testing for every mix to EN 1170-7 and EN 1170-8 (DIHM) by UKAS-accredited external laboratories.
  • Random product testing on customer-selected panels by UKAS-accredited external laboratories.
